My returns are based on full cash purchase of the properties, as it is hard to compare the attractiveness of properties at different price ranges when only calculating down payment or properties that need very little rehab/updates. I did think about the scores assigned to each factor, but I believe tax deductions are a SIGNIFICANT factor when comparing passive income steams.

Starting a blog is one of the most popular side hustles to earn online income. This is because whether you have 10 people or 10 million reading your content, the amount of your effort to write an article is the same. Websites have low start-up costs and you can literally buy your domain, launch your site and have a few pages created in less than an hour. You won’t start making money right away, but you will be building towards that first $1 of income.

Unfortunately, I can’t answer that conclusively one way or the other. It all depends on you, what you like to do, your work ethic, personality, etc. If you are a good writer perhaps you could write a book and make money that way. Or, you could start your own website and do affiliate marketing. Just because you are young it doesn’t mean you can’t make money doing at least a few of these ideas. I wish you luck in your money making efforts!
You are also free to choose a fund that is based on any index that you want. For example, there are index funds set up for just about every market sector there is — energy, precious metals, banking, emerging markets — you name it. All you have to do is decide that you want to participate, then contribute money and sit back and relax. Your stock portfolio will then be on automatic pilot.
One aspect you might want to add to your scoring is “inflation protection”. At one end, bonds and CDs generally pay a fixed nominal coupon that doesn’t rise with inflation. Stock dividends and Real estate rents (and underlying property value) tend to. Not reallly sure how P2P lending ranks- though I suppose the timeframes are fairly short (1 year or less?) and therefore the interest you receive takes into account the current risk free rate + a premium for your risk. Now that I think about it, P2P lending probably deserves a lower score in the activity column than bonds too (since you probably need to make new loans more often).
Which all goes back to my point – since companies change in a lot of unpredictable ways, it makes more sense for passive income to just ride the market by investing in a Total Domestic Stock Market, Total Bond Market, and Total International index funds, with allocations that depend on your goals and time horizon. For income, withdraw 4% or less, depending on what research you believe, and you’ve got a pretty low risk strategy.
Creating passive income is the key to retiring, especially retiring early. If you want to retire early with the stock market you will have to save a huge amount of money, because that money has to last so long and retirement calculators depend on you using your investment to fund your life. With passive income you will have income coming in as long as you own the investment, without every eating away at the principle invested. Creating passive income may take more work than investing in the stock market, but I think it is well worth the extra effort!
